Experimental investigation for thermal performance enhancement of various heat sinks using Al2O3 NePCM for cooling of electronic devices

Imran Zahid ab, M. Farhan a, M. Farooq a, M. Asim a, M. Imran c Abstract Electronic devices are being used extensively for different applications, where the thermal management of these devices is still a critical challenge due to rapid miniaturization, high heat flux and constantly rising temperature. Phase change materials (PCMs) based thermal management is adopted, but the low thermal conductivity limits their use in temperature-controlled electronic devices. Nano-enhanced phase change materials

Effects of Cr-addition on ageing response of an Al–Si–Mg die cast alloy

Effects of Cr-addition on ageing response of an Al–Si–Mg die cast alloy

In the present study, high pressure die-cast samples made of Al-7wt.%Si–Cr–Mg alloys with varied Fe contents (0.11 wt%, 0.26 wt% and 0.32 wt%) were tensile tested under as-cast and T5 heat-treated conditions, in comparison

Temperature dependence of mechanical strength in HPDC Mg–6Y–3Zn–1Al alloy with LPSO phase

Temperature dependence of mechanical strength in HPDC Mg–6Y–3Zn–1Al alloy with LPSO phase

Xin Yu a, Yafeng Li b, Yang Bai a, Wei Huang c, Bing Ye a, Xiangyang Kong d Abstract The temperature dependence of mechanical strength including yield strength (YS) and ultimate tensile strength (UTS) in HPDC WZA631 alloy is investigated in a wide temperature range from room temperature (RT) to 350 °C. It is found that at 25–300 °C, YS and UTS do not drop markedly, from 173 MPa and 274 MPa at RT to 113 MPa and 170 MPa at 300 °C, respectively. While

Fig. 3. (a) Schematic of four-point reversed bending set-up used in this study. Dimensions in mm. (b) Picture of the bending fatigue test set-up. The specimen was fixed by four fixtures, where two outer fixtures were connected to upper moveable shaft for applying the loading. The two internal fixtures were connected to the fixed base in the bottom. Between the fixture and the shaft/base were thin steel spring to ensure that the specimens can bend flexibly. To show the details more clearly, the distance between each fixture shown in the picture is larger than the actual distances used in this study.
